Versuchsvorschrift

A mixture of 3,6-dichloropyridazine (3 g, 20.14 mmol) and hydrazine monohydride (1 g, 20.14 mmol) was heated in a sealed tube to 80° C. for 5 hours. Solvent was evaporated and the crude was used in the next step without purification (3.56 g, 100%). LCMS (method B): [MH]+=145.1, tR=0.57 min.
